## Docs

- [Inference Router Quickstart](https://you.com/docs/guides/inference-router/quickstart.md): List your available models, send a Chat Completions or Anthropic Messages request, and stream the reply from the You.com Inference Router with an OpenAI or Anthropic SDK.
- [Inference Router Tool Calling](https://you.com/docs/guides/inference-router/tool-calling.md): Declare function tools on the Inference Router, receive tool calls, send results back, and combine them with the web tools.
- [Inference Router Reasoning](https://you.com/docs/guides/inference-router/reasoning.md): How reasoning models behave on the Inference Router: reasoning tokens, reasoning_content, reasoning_effort, and output limits.
- [Web Tools](https://you.com/docs/guides/inference-router/web-tools.md): Declare web_search, web_extract, or client:web_search on Chat Completions, or Anthropic's web_search server tool on Messages, to ground a model's answer in live web results.

# Inference Router Overview

## What Is the Inference Router?

The Inference Router serves language models from one base URL, `https://api.you.com`, with one You.com API key. It exposes an OpenAI-compatible endpoint at `/v1/chat/completions` and an Anthropic-compatible endpoint at `/v1/messages`, so existing OpenAI and Anthropic SDKs work by changing the base URL and key. The [Quickstart](/docs/guides/inference-router/quickstart) sends a first request.

Declare a `web_search` or `web_extract` tool and the router runs You.com searches and page fetches for the model, then returns the answer with the sources it used. See [Web Tools](/docs/guides/inference-router/web-tools).

## Endpoints

For a complete list of endpoints, see the [API reference](/docs/api-reference/inference-router/create-chat-completion).

| Endpoint                                       | Format                         | API reference                                                                       |
